Genesis 15:7 And he said unto him, I am the Lord that brought thee out of Ur of the Chaldees, to give thee this land to inherit it.
In true Biblical worship we find that God “takes us out” so that He can “bring us in”. The Father had to get Abraham out of the land of Ur in order to bring him into the land of promise.
So it is with us. We are in the world, but not of the world. Our faith is not natural but supernatural. God calls us out of the world, out of sin, out of the life and nature of old Adam, out of walking to fulfill the desires of the flesh INTO a Christ-like life.
God calls us into a deeper relationship and fellowship with Him. God calls us into a walk of practical righteousness and holiness. God calls us into His places in the heavenlies to sit down with Him. Our act of worship should be our natural response to the covenant that God made with us. We have nothing to bring to the table except our lives and a desire to worship the king of glory.
Genesis 15:8-12 And he said, Lord God, whereby shall I know that I shall inherit it?  And he said unto him, Take me an heifer of three years old, and a she goat of three years old, and a ram of three years old, and a turtledove, and a young pigeon.  And he took unto him all these, and divided them in the midst, and laid each piece one against another: but the birds divided he not.  And when the fowls came down upon the carcases, Abram drove them away.  And when the sun was going down, a deep sleep fell upon Abram; and, lo, an horror of great darkness fell upon him.
Genesis 15:17-18 And it came to pass, that, when the sun went down, and it was dark, behold a smoking furnace, and a burning lamp that passed between those pieces.  In the same day the Lord made a covenant with Abram, saying, Unto thy seed have I given this land, from the river of Egypt unto the great river, the river Euphrates:
The Father walked between the two pieces establishing the covenant with Abraham while Abraham slept. The Lord Jesus Christ did the same in the garden as the disciples slept.
